Features

• High-Voltage CMOS technology

• Symmetric row drive (reduces latent imaging in

ACTFEL displays)

• Output voltage up to +230V

• Low power level shifting

• Source/sink current minimum 70 mA

• Shift register speed 4.0 MHz

• Pin-programmable shift direction

Description

HV7022 is a low-voltage serial to high-voltage parallel

converter with push-pull outputs. It is especially suited

for use as a symmetric row driver in AC thin-film elec-

troluminescent (ACTFEL) displays. HV7022 offers 34

output lines, a direction (DIR) pin to give CW or CCW

shift register loading, output enable (OE), and polarity

(POL) control. After data is entered on the falling edge

of CLK, a logic high will cause the output to swing to

VPP if POL is high, or to GND if POL is low.
